SHEET-METAL WINDDW SCREEN.

Application filed June 30,

This invention relates to window screens.

()bjects of this invention are to provide an all metal window screen of novel construction, which may be readily manufactured in a simple and easy manner, and which is so constructed that it will fit tight in any window, although slight variations in the dimensions of the window may occur.

Further objects of this invention are to pi ovide a novel form of window screen in which a yielding packing is employed in corn junction with, and forming a part of the screen itself, so that the packing will fitagainst the face of the window casing, and

" will prevent the formation of cracks which would permit the entrance of insects.

Further objects are to provide a novel form of metal screen so constructed that the channel for the reception of the packing forms a reenlorcement or stiil'ening adjacent the screen margin, and in which such channel cooperates with the retaining member to readily retain the packing in position, in a simple and eilicacious manner.

An embodiment of the invention is shown in the accompanying drawings in which:

Figure 1 is an elevation of a window equipped with a screen constructed in accordance with this invention, with parts of the screen casing or marginal portion broken away;

Figure 2 is a transverse sectional view on the line 2-2 of Figure 1;

Figure 3 is a sectional view on the hue 3-3 of Figure 1.

Referring to the drawings, it will be seen that a window casing 1 has been disclosed as of the usual construction. This window casing is adapted to receive the screen upon its outer face in distinction to the usual mode of mounting the screen within the casing. By mounting the screen in tl'le 1111-111101 de scribed, it is possible to use one size of: screen for a number of different sized windows which heretofore has been impossible.

Ftcferring to the drawings, it will be seen that the screen is provided with a margmal portion formed oi an inner and an outer sheet metal plate 2 and 3 (see Figures 2 and 3) which are integrally joined at their outer ends and receive between them the screen proper or. wire mesh member 4. Thls marginal portion is formed with a channel completely around its marginal portlons, as shown most clearly in Figures 2 and 3. The channel is a semi-circle in cross section, as

indicated at 5 in Figure 2 for the side and top marginal portions, and is approximately a quarter circle for the lower marginal portion, as shownat 6 in Figure 3. W'ithinthe channel, a packing or gasket is positioned. This packing may be of rope-like formation sufiiciently yielding to be readily positioned within the channel and to yield sufiiciently to close all gaps between the marginal portions and the window casing. This packing be, for example, formed of fibrous ma terial, steel wool, rubber, or other suitable material provided it has the characteristics noted above. It is retained in place by means of loops of wire, as indicated at 8, which are passed through apertures formed in the channel portion and extend through the packing, the ends of the wire being twisted together, as shown. Thus an extremely simple retaining means is employed for holding the packing in place.

At the lower portion of the window, the packing 7 bears against the window sill 9, as shown in Figure 3, and completes the tight joint entirely around the screen.

It is to be noted that the wire screen er:-

tends between the marginal members and is received in its curved portion. This curved portion, therefore, performs three functions. In the first place, it aids in retaining the wire mesh screen l, which may, if desired, be spot welded thereto, or riveted, or otherwise secured. In the second place, it increases the strength of the marginal portion against distortion due to its channel shape. In the third place, it forms a chan nel or pocket for the reception of the pack 111g.

All of these results are attained without an undue increase in the expense of the screen, and also all of these features are highly desirable and permit a novel mode oi functioning of the screen, as it completely seals all crevices, and also permits the use of the screen upon ditlerent sized windows, as the screen merely contacts with the outer face of the window casing.

Obviously, the screen ma be provided with the usual hangers or ttings 10 (see Figure 1), whereby it may be suspended, and with the usual latching means or adj usting means (not shown).

It will be seen that a metal screen has been provided of novel construction, which will efi'ectively seal against the window casing, and which may be employed with a large number: of different sized Windoivs Without altering the construction ofthe WiDClOWill any manner. Further, it Will 06 seen that the screen may be very cheaply immune tured and may be readily applied-j Although the invention has been described in considerable detail, such. description" is intended as illustrative rather than'limiting as the invention may be variously embodied and asthescope of such invention is tO 'be determined as 'claimed.
